getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

Specified by:

getTableOperationType in interface TableProcedureInterface

Specified by:

getTableOperationType in class AbstractStateMachineNamespaceProcedure<ModifyNamespaceState>

Returns:

the operation type that the procedure is executing.

getNamespaceName

protected java.lang.String getNamespaceName()

Specified by:

getNamespaceName in class AbstractStateMachineNamespaceProcedure<ModifyNamespaceState>
